Incidentally, it is my current understanding that anything that I do with an "ip route" command will go away on a reboot, therefore if I somehow screw up the routing on this box completely all I have to do is reboot it and I'll be back to what I had before. Which is not a bad thing at the moment. Once I have this nailed down should I put the "ip route" commands into /etc/rc.local? Or is there a better place?
Use /etc/sysconfig/network/route-<interface> file(s).
